With a current price of $168.99, it provides a strong Clean Air Delivery Rate (CADR) of 250 for smoke, dust, and pollen, making it ideal for households with pets or allergy sufferers. Its modern Scandinavian design and quiet operation, ranging from 23 to 50 dB, make it suitable for bedrooms and living areas.
Overview of the PuroAir 130i
The PuroAir 130i is a budget-friendly air purifier that covers areas up to 600 square feet and is priced at $99.99. This model boasts a powerful 3-layer filter that claims to remove up to 99.9% of pollutants, including smoke and pet dander. Although it has a smaller coverage area compared to the BLUEAIR Blue Pure 311i Max, its fast purification rate allows it to clean rooms efficiently in about an hour. The PuroAir 130i also features Wi-Fi connectivity, enabling users to control settings conveniently through its app.
Filtration Technology
When it comes to filtration technology, the BLUEAIR Blue Pure 311i Max utilizes advanced HEPASilent technology, combining mechanical and electrostatic filtration to achieve high efficiency while maintaining low noise levels. It captures 99.97% of airborne particles, including allergens as small as 0.1 microns. In contrast, the PuroAir 130i employs a 3-layer filter with CarbonTech, claiming to filter particles 700 times smaller than a human hair and remove 99.9% of pollutants. While both purifiers offer effective filtration, the BLUEAIR's superior CADR and coverage range may be more beneficial in larger spaces.
Smart Features
The BLUEAIR Blue Pure 311i Max excels in smart features, offering app control that allows users to monitor air quality, adjust fan speeds, and track filter life from anywhere. Its built-in sensors automatically adjust operation based on pollution levels. On the other hand, the PuroAir 130i also includes Wi-Fi capabilities, allowing for remote control via its app. While both products provide smart features, the comprehensive monitoring and automatic adjustments of the BLUEAIR offer a more advanced user experience.
Noise Levels

The PuroAir 130i's sound levels are not specified, but it is designed to operate quietly as well, ensuring a comfortable environment. Given the BLUEAIR's QuietMark certification, it may be the better choice for those sensitive to noise.
Price Comparison
The PuroAir 130i is significantly more budget-friendly at $99.99, making it about 41% cheaper than the BLUEAIR Blue Pure 311i Max, which is priced at $168.99. This price difference may appeal to consumers looking for a cost-effective solution for smaller spaces. However, while the PuroAir offers a lower initial investment, the BLUEAIR provides larger coverage and advanced features, which could justify the higher price for some users.
Maintenance and Longevity
Both air purifiers require regular filter replacements to maintain their efficacy. The BLUEAIR Blue Pure 311i Max's app helps track filter life, making maintenance easier. The PuroAir 130i also emphasizes its reliability with a 2-year risk-free warranty, appealing to consumers concerned about product longevity. While both models are designed for easy maintenance, the tracking features of the BLUEAIR provide additional convenience.
Which should you buy?
Choosing between the BLUEAIR Blue Pure 311i Max and the PuroAir 130i depends on your specific needs. If you require a powerful air purifier for larger rooms and value advanced smart features, the BLUEAIR Blue Pure 311i Max is the superior option despite its higher price. However, if budget is a primary concern and you need a purifier for smaller spaces, the PuroAir 130i offers effective filtration at a more affordable price. Ultimately, consider your room size and personal preferences before making a decision.
